Comment 4 Bogdan Onofriuchuk 2025-05-05 16:45:19 UTC 
Can you collect the logs please, because I don't have any disks. 
1. In terminal execute: QT_LOGGING_RULES="org.kde.applets.devicenotifier=true" plasmoidviewer -a org.kde.plasma.devicenotifier &> log.txt
2. Reproduce the bug
3. stop the process in terminal
4. attach the file log.txt here
Comment 5 Patrick Silva 2025-05-05 16:57:59 UTC 
I get a segfault when the inserted disc is recognized:

$ QT_LOGGING_RULES="org.kde.applets.devicenotifier=true" plasmoidviewer -a org.kde.plasma.devicenotifier &> log.txt
Segmentation fault (core dumped)
Comment 6 Bogdan Onofriuchuk 2025-05-05 18:07:52 UTC 
Yes. Looks like a bug in the plasmoidviewer. Can you use another command:
QT_LOGGING_RULES="org.kde.applets.devicenotifier=true" plasmawindowed org.kde.plasma.devicenotifier &> log.txt
This command should work correctly.
